Abstract:
The present study describes the presence of os inca, incomplete metopic suture with asymmetrical frontal sinuses and multiple sutural deformities in a skull bone. Os inca has been reported to be associated with other cranial deformities. However, the present study, besides reporting os inca and associated sutural abnormalities, also highlights the presence of an unusual pterion in such cases. The aim is to provide anatomical insight into the morphology of sutures, frontal sinuses and associated cranial abnormalities. These are important findings which may be relevant for surgeons and radiologists in clinical practice.

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
